Toyota is famous for their wildly colorful cars in the TRD lineup. Magma Orange, nori green, and that like Smurf blue color.
Ford has a vibrant blue as well. GM doesn’t deviate from bare colors much, but Ram/dodge will as well. Patriot blue, fire engine red, delmonico red, and plum crazy.
Porsche has full paint to sample.
Mercedes is basically famous for black cars so…
Anyways, cars have colorful variants, just the consumer base either isn’t willing to wait for the order, or they don’t want to pay the extra 500-900 dollars most non-standard paint color costs.
Also, a lot of manufacturers offer up tri coat white metallic which obviously looks boring from afar, but up close is very vibrant.
Toyota does a special color every year for their TRD lineup.
If you’re willing to count the black roof combo option the Corolla has 15 color options or 8 full color options. Red and blue are offered. Just no yellow or orange.
People just don’t want to wait for a special car and want whatever is on the dealer lot. So they make as many of those in boring colors.
